IVILLIAM II. STRONG, OF SARDINIA, NEW YORK.

THILL-CO UPLING.

SPECIFICATION forming part of Letters Patent No. 617,972, dated January 17, 1899.

Application filed Qotoher 18, 1898. Serial No. 693,924- (No model.)

To aZl whom it may concern.-

Be it known that 1, WILLIAM H. STRONG, a citizen of the United States, residing at Sardinia, in the county of Erie and State of New York, have invented certain new and useful Improvements in Thill-Oouplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to thill-couplings, and more particularly to that class known as the antirattler type.

The object of the invention is to provide a simple and inexpensive coupler of this character which may be readily attached to the thills now in general use and which will serve the purpose of preventing rattling.

With this object in view the invention consists in certain features of construction and combination of parts, which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective View of the axle, axle-clip, thilliron, and my improved coupling, showing the parts assembled for use. Fig. 2 is a side elevation of the antirattler removed. Fig. 3 is a similar view of the bolt before its lower arm is bent over upon the coils of the springarms.

In the drawings, 1 denotes the axle; 2, the axle-clip, having parallel ears 3; 4, the clipyoke, and 5 the thill-iron. These parts may be of any well-known or approved construction.

6 donotes the bolt, having an arm 7 which is inserted through the ears of the axle-clip and through the eye of the thill-iron. This bolt has a downward extension 8 and a lateral extension 9, which is parallel with the section 7. The extension 9 is preferably tapered and has its extreme end projecting upwardly, as shown at 10.

11 denotes a compound spring-arm having a series of reversely-curved bends 12, which project upwardly between the ears of the clip and are curved to conform to the curved end of the thill-iron. The lower ends of the compound arm are formed with spring-coils 13, that are slipped on the lower arm of the bolt and held in position by bending the tapering end 10 of the bolt over and parallel with said arm, as shown in Fig. 2. The free ends of these coils project downwardly to form spring-arms 14, which are provided with eyes 15, in which is hung a bail 16, which is adapted to be swung back and be engaged with the rear end of the clip-yoke, thus forcing the compound arm, with its bends, in firm engagement with the eye of the thill-iron, thereby preventing rattling.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of the invention will be readily apparent without requiring an extended explanation.

It is evident that a device thus constructed may be applied to any of the well-known forms of thill-oouplings now in use and when in position will effectually prevent the parts rattling.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-- In a thill-coupling, the combination with the axle-clip having parallel ears, the clipyoke and the thill-iron, of a bolt inserted through the ears of the clip and the thilliron and having a downwardly-extending end and a laterally-projecting portion parallel with the main portion and formed with a tapering extremity, a compound arm having at its upper end reversely-curved bends curved longitudinally of their length to conform to the rounded end of the thill-iron and having at their lower ends coils that are slipped upon the lower laterally-projecting portion of the bolt, which then has its tapered end bent down to prevent the coils slipping from said portion, said coils having downwardly-projecting arms and formed with eyes, and a bail hung in said eyes and adapted to engage and be retained by the rearwardly-project-ing end of the clip-yoke, substantially as described for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM H. STRONG.
